plz follow me and mark as brainalist
Explanation:
In test-tube A, the boiled rice contains starch. When we add 1-2 drops of iodine, the combination turns in the shade of blue-black. This indicates the presence of starch in the test tube A.
In test-tube B, the starch of rice converts into sugar on digestion. Thus, the colour of iodine will not change.
